Corrections and clarifications

It was not quite correct to say, as we did in a column, page 7, Media, June 5, that Andy Coulson, the editor of the News of the World, had raised its circulation to 4m. The ABC figures show that the NoW sold 3,551,378 copies in April this year compared to 3,639,243 in April 2005.

In the People column, page 15, June 1, we said that the arts centre which Rafael Vinoly is designing for Colchester would be his first building in Britain. In fact, it is the second. Vinoly's performing arts centre in Leicester has already been under construction for almost a year.

We stated in error that a charity, Addaction, had saved £10,000 by installing new computer systems (From Cinderella to Rockefeller, Business Sense, May 26). appiChar, the company which installed the systems, has pointed out that, in fact, the charity concerned was Compass.

The sports commentator Kenneth Wolstenholme became Kevin Wolstenholme on page 8 of the World Cup 2006 supplement published with the Guardian on June 5.

Martina Navratilova's book, Shape Your Self (page 13, G2, May 29), is published in the UK by Time Warner.

Yesterday's correction suggesting that the sun as seen from Whitby sets over land and not over sea, was itself incorrect. For part of the year the north-facing location of Whitby ensures that the sun both rises and sets in the sea.
